Pulmonary edema that isn't caused by increased pressures in your heart is called noncardiogenic pulmonary edema. In this condition, fluid may leak from the capillaries in your lungs' air sacs because the capillaries themselves become more permeable or leaky, even without the buildup of back pressure from your heart.
So in other words, ambulatory medical care is a term for almost all of the medical appointments and treatments people receive regularly.
Ambulatory surgery centers (ASCs) are medical facilities that specialize in elective same-day or outpatient surgical procedures. They do not offer emergency care. It means that the patients treated in these surgical centers do not require admission to a hospital and are well enough to go home after the procedure.
